The thing you must appreciate Ray is that A7's are very over-geared, so the speed you will reach on the road has more to do with air resistance, weight, gradients and wind direction than it has to do with engine performance. When comparing speeds then look at cars of similar size and weight, and with similar overall gearing. Based on replies above you ought to be able to hold 45 or 50 on a decent road; but this alone is a doubtful barometer of engine health.
